Answers
Answer:
500
Step-by-step explanation:
Let there were a total of x number of customers.
As 125customers choose chocolate flavor as their favorite which is 25% of the total customers surveyed, so
25% of x = 125
0.25x=125
x=125/0.25=500
Therefore, the total number of customers surveyed is 500.

A insurance salesperson earns a salary of $4,200 per month plus a commission of 3% of sales. How much must the salesperson have to sell to make an income of at least $4,500?
Answers
Answer:
x = 10,000
Step-by-step explanation:
commision earned = $4500. - $4200
commision = 300
therefore:
commision = 3% of the amount of the sales
300 = 3% of x( the price isn't known)
300 = 3/100 * x
300 = 3x /100
multiplying both sides by 100
300 x 100 = 3x/100 x 100
30000 = 3x
Divide through by 3
x = 10,000.
the amount of the sales = 10,000
______________
To check
commision = 3% of 10,000
commision = 300

What is the exact value of tan(105°).

-2-√3
Answers
The exact value of tan(105°) is -2 - √3.
What is Tangent function?Tangent function of an angle in a right angled triangle is defined as the ratio of the opposite side to the adjacent side.
Given that, we have to find the exact value of tan(105°).
We know that,
105° = 60° + 45°
tan(105°) = tan (60° + 45°)
We know,
tan (A + B) = (tan A + tan B) / (1 - tan A tan B)
So,
tan (60° + 45°) = (tan 60 + tan 45) / (1 - tan (60) tan (45))
tan 60 = √3 and tan 45 = 1
tan (60° + 45°) = (√3 + 1) / (1 - √3)
Multiplying both numerator and denominator by (1 - √3),
= (√3 + 1)² / (1 - 3)
= -(3 + 2√3 + 1) / 2
= -(4 + 2√3) / 2
= -(2 + √3)
= -2 - √3
Hence the value of tan(105°) is -2 - √3.

Part C: Solve the following inequality: -5(x + 1) > 30 (2 points)
Part D: f(x) = 4x - 3. Find f(5) (2 points)
Answers
Answer:
Part A) x = -3
Part B) x = 1, x = -7
Part C) x < -7
Part D) 2
Step-by-step explanation:
Part A)
2(x - 3) = 3x - 3
open the parenthesis
2 * x - 2 * 3 = 3x - 3
2x - 6 = 3x - 3
subtract 2x from both sides
2x - 2x - 6 = 3x - 2x - 3
-6 = x - 3
add 3 to both sides
-6 + 3 = x
-3 = x
Part B)
|2x + 6| = 8
split this into two equations:
2x + 6 = 8
&
2x + 6 = -8
2x + 6 = 8
2x = 8-6
2x = 2
x = 1
2x + 6 = -8
2x = -8 - 6
2x = -14
x = -7
Part C)-5(x + 1) > 30
open the parenthesis
-5x - 5 > 30
add 5 to both sides
-5x > 35
divide both sides by -5
x > -7
since you divided by a negative, flip the sign.
x < -7
Part D)
f(x) = 4x - 3
substitute x for 5
5 = 4x - 3
5 + 3 = 4x
8 = 4x
2 = x

How many four-digit personal identification numbers (PIN) are possible if the PIN cannot begin with a 0 and the PIN must be an odd number?
ANSWER B: 4,500
The number of 4 digit personal identification numbers (PIN) is 4500
What is a PIN?A PIN is a security code that is used for verifying identities
There are 10 numerical digits i.e. 0 - 9
Since the 4 digit personal identification numbers (PIN) cannot begin with 0, then the first character can take any of 9 digits
The other three characters can take any of the 10 digits.
So, the number of PIN is:
PIN = 9 * 10 * 10 * 10/2
Expand
PIN = 4500
Hence, the number of 4 digit personal identification numbers (PIN) is 4500

Step-by-step explanation:
We can start by looking at it as a ratio, so 4 divided by 20 and 4/20 = 0.2, so that would be 20% viewing 1=100%.
Another way is
20 here is 100%, and for 20 to equal 100, we have to multiply it by 5. To balance it out, multiply the top by 5 as well, and 4 * 5 =20. Therefore, 4/20 = 20%

3. String A is 35 centimeters long. String B is 5 times as long as String A. Both are necessary to create a
decorative bottle. Find the total length of string needed for 17 identical decorative bottles. Express your
answer in meters.

Answers
Answer:
The total length of string needed for 17 identical decorative bottles is 35.70 meters
Step-by-step explanation:
Let us solve the question
∵ String A is 35 centimeters long
∵ String B is 5 times as long as String A
→ Multiply the length of A by 5 to get the length of B
∴ The length of string B = 35 × 5 = 175 cm
∵ Both are necessary to create a decorative bottle
∴ The length needed for 1 bottle = 35 + 175 = 210 cm
∴ Each bottle needs 210 cm to be decorated
∵ There are 17 identical bottles
→ Multiply the length needed for 1 bottle by 17
∴ The total length needed = 17 × 210 = 3570 cm
∴ The total length needed to decorate 17 bottles is 3570 cm
∵ 1 meter = 100 centimeter
→ Divide the total length by 100 to express it in meters
∴ 3570 cm ÷ 100 = 35.70 m
The total length of string needed for 17 identical decorative bottles is 35.70 meters
